There is a column of numbers arranged according to certain rules as 1, - 3, 5, - 7, 9 If the sum of the three adjacent numbers is - 201, find the three numbers?
Let one of the three numbers be X. according to the meaning of the question, we get: (- X-2) + X + (- x + 2) = - 201. The solution is: x = 201, - x + 2 = - 199, - X-2 = - 203. Answer: the three numbers are - 199, - 201, - 203
